How bad is your gas mileage?

[RockBit]

I have a 482 cid FE, 3.54 rear, and TKO600 with .64 5th gear. In the city I get 8 mpg on 93 octane pump gas, and I get 12 mpg on the highway. It purrs along at 2,000 rpm at 70 mph.

I'm 35 cubic inches smaller, but otherwise I'm exactly the same on all the other numbers. And I really enjoy when I'm out on a remote highway and have the road to myself and hit the "quiet spot" in my revs, at about 2200 RPM, and just cruise at 75 MPH. It actually restores mental health.

That’s very encouraging. It implies mine is tuned ok since I know yours is.
